Custom software systems for businesses that have outgrown spreadsheets and generic SaaS.

I design and build systems for operations, payments, bookings, memberships, education, healthcare and commerce.

I build business software that replaces spreadsheets, disconnected tools and manual workflows.

About me

When your business needs more than a website, but doesn't need a massive software company.

  • Automate operations
  • Centralize payments and data
  • Replace fragmented tools with one clear system

I build workflows to deliver practical systems that businesses actually use.

How I work

Depending on the project and its complexity and status I follow any of these steps:

Understand the business

We map the workflows, users, constraints and bottlenecks before writing code.

Design the smallest useful system

We define what actually needs to be built—and what doesn't.

Build the core workflows

We focus on the operations that create measurable value for the business.

Launch and improve

The system evolves as the business learns what it actually needs.

Who this is for:

This is for you if...

  • Your team runs important operations in spreadsheets.
  • You're paying for several tools that don't talk to each other.
  • Your workflow doesn't fit generic SaaS.
  • You're manually processing bookings, payments or memberships.
  • Your business has grown beyond the tools you started with.
  • You need software that works around your business—not the other way around.

If that‘s you, we should talk.

The Kind of System I Build:

Things like:

Operations

Internal dashboards, workflows, scheduling, automation and business management.

Payments & Commerce

Payment flows, ecommerce, subscriptions, orders and customer portals.

Education

LMS platforms, student management, courses, memberships and payments.

Hospitality

Reservations, booking workflows, guest experiences and operational systems.

Healthcare

Patient-facing systems, scheduling, payments and internal workflows.

More about me

Hi and welcome! I‘m Mikhail or Jail for family and friends, that is pronounced in Spanish [h'aɪl].

I‘m a Senior Software Engineer with 10+ years shipping production systems, moving into Product Engineering — thinking about the business outcome a system needs to produce, not just the code that ships it.

Thanks for stopping by. Read the full story.

Testimonials

"He is a focused and very capable front-end programmer. He can use everything from the basics of web development (html. css, javascript) to researching new languages and frameworks you haven't worked with. Also Mikhail is a programmer very interested in the communities that are around him. I definitely recommend to work with him."

- Ivan Mejia Fabela

"Mikhail is a solid developer with strong experience on Javascript, NodeJS, AgularJS. He designed and developed uncommon user interfaces with short deadlines an deliver the updates on production."

"He was able also to understand and implement correctly the four levels of maturity of a REST API, to work with ElasticSearch, Apache Jena and with Java EE RESTFUL services. He also has experience on MongoDB, PostgreSQL, and excellent knowledge of BASH and scripting languages. If you don't know how to automate stuff on Linux, surely Mikhail knows how to do that for you. He knows a lot of BASH and terminal consoles."

- Víctor Polo de Gyvés Montero

I had the pleasure to work with Mikhail for two years. During this time he was always eager to learn new languages and frameworks and to adhere to best practices, so much that he was able to deliver not only on the front-end but also on the back-end of several projects. He always made the projects his own and never hesitated to suggest a different approach if he thought it best. He would be an asset to any dev team that needs someone to adapt and learn quickly, work under pressure and deliver to the highest standards

As a foreigner, it was precious to be welcomed on such an inclusive place like XalapaCode by all members and organizers, but specially to some people like Mikhail. He as the Founder of XalapaCode, introduced me to the community, providing me space for participating in many fronts, supporting my initiatives, not just as Member, but also as Organizer.

His charisma and insights from the industry are one of the strongest points of our precious community, facilitating discussions, meetings, being more than a notable Software Engineer, but also leading people and welcoming anyone that wants to be part of this mission of making community, sharing knowledge and while having fun.

He has patient to guide, doesn't matter if you are a fresh-starter or an university student (like so many that he have been impacting over these years here in Xalapa). His contributions in the context of the city and for students at Universidad Veracruzana and professionals like me, are as remarkable as precious.
